Acorn 4
A brand new UI, non destructive filters and layer styles merged together in one great bag of awesome, curves, much improved vector tools, and speed. And that’s just some of the big stuff. There’s a ton of little things which when added all together make Acorn feel and work better than it ever has.
Update (2013-05-11): Gus Mueller:
I could set the release to May 3rd, and then when I was ready I could just push the release date back to May 1st! Since May 1st was already here (and gone in some time zones) Acorn 4 would roll out everywhere at the same time, which was exactly what I wanted.
